WINDOW APrLiAN'oE.

Application mea'm so, v1925. Serial 110, 16,957.

This invention relates to a simple and compact apparatus whereby an unweighted window-sash or other movable object may be either raised or lowered to any desired extent 5 in its window frame, above or below the normal,position of the sash or other object with respect to its frame.

The invention is especially useful when applied to the more or less light-weight sashes found in frame houses and the like, and also when applied to the windows of railway cars and in similar situations. In

this case the invention has s ecial merit, because the window-sash may e supported either above or below its normal closed position permitting the windowto be open either at the top or the bottom, as desired, by means of the same sash.

Various other objects and advantages of the invention will be obvious from the following particular description of one form of mechanism embodying my invention or from an inspection of the accompanying drawings; and the invention also consists in certain new and novel features of construction and com-' binations of parts hereinafter set forth and claimed.

In the accompanying drawings, in which Fig. 1 is an elevation partly in section of the ordinary window-sash equipped with the invention;

Fig. 2 shows the device when employed for car window use,

Fig. 3 is a front elevation of the sashsupporting device;

Fig. 4'is a side elevation thereof; Fi 5 is a transverse sectional view of the friction element;

Fig. 6 is a perspective view of a detail of a member of the friction element; and

Flg. 7 1s a horlzontal sectlonal View through the friction device showing the manner of mounting the same in the windowsash, and engagement thereof with the window frame.

In the embodiment of the invention herein selected for illustration, 1 indicates the window-sash frame, 2 the upper sash,and 3 the lower sash, which latter is to be held in ad justed position by the improved device. This lower sash is provided with the usual handgrips 4. Suitably mounted in the side members of the window-sash, as in mortises 5, is a bow-spring member 6, which is rigidly held 56 at one end 7 by means of a screw, and movthe expense of renewing the frame members.

ably held at the opposite end 8 by means ofa second screw engaged by a slot 9, Fig. 3, of the bow-spring member 8. The spring member is provided with the lugs 10, in which are rigidly mounted the studs 11 of a friction 60 ratchet 12. This ratchet is provided with suitably formed longitudinal depressions 13- within which are carried roller friction-pins 14. The ratchet member 12 and the pins 14 are enclosed within a short sleeve 15, which is preferably knurled as at 16 to aiford a friction hold on thewindow frame. It will be seen. from an inspection of Fig. 5 that while the sleeve 15 is capable of rotating freely to the right or clockwise on the friction ratchet 7o 12, the moment an attempt is made to rotate it in the opposite direction, the pins 14 will roll to the outer extremity of the depressions 13 and hold the sleeve 15 rigidly fixed with reference to the ratchet member 12. Inas- .7'5 much as the ratchet member 12 isrigidly mountedin the lugs 10 of the bow-springs 6,

it is evident that the sleeve 15 cannot rotate counter-clockwise, for example as shown in Fig; 5, at all, to any. great extent. The friction devices'areso mounted within the window-sash 3 that the sleeves 15 thereof may rotate freely when the window is raised, but the moment the sashis released by the operator, the friction member will resist any lowering movement of the sash and hold the window in the position to which it is moved.

In order that the wear of the friction memher or knurled sleeve 15 on the window frame may not finally wear the bearing part of the frame in a groove, which might eventually 4 defeat the object of the invention, I provide the bearing part of the frame with a wearstrip 17, preferably of thin fiber board or the like, which though having some capacity to. yield and, therefore, permit the window to be lowered b pressure, is nevertheless much more dura le under friction than wood, and furthermore, may be renewed easily without In the embodiment of the invention illustrated in Fig. 2, the parts of the friction device heretofore described may be as set forth, but in this instance, the device is shown as employed with a car window-sash 18. In 105 many instances, car window-sashes are arranged to be raised from their normal closed position: in some'instances, to be lowered below the window-sill19. My invention, therefore, is intended to provide for both of these i 10 taken place,

provide the bearing faces of the contingencies and, moreover, may be employed with a window-sash, which may be both raised from normal closed position with respect to the window-sill, or may be lowered below the window-sill as may be desired.

As a further provision for preventing accidental dropping of the window when held in adjusted position by the friction device, I

windowframe at one or both sides of the sash with a more or less fluted or wavy bearing strip 20. In steel car construction, this strip may be made of sheet metal and the slight convolu tions thereof present curved projections to the travel of the friction sleeve 15 so that when the sleeves rest, in the depressions, it will require a very considerable jar to shake the sash loose and permit it.to drop. It will be seen also that in this car-window construction the sash is provided with finger holds 21 both at top and bottom so that the sash may be easily raised above-the' silhor with equal facility, below the sill, it being understood that the end frame members of the windowsash will always be exposed either below the window cap or above the window-sill respectively so as to be within reach of the operator. In this embodiment of my invention, it will be seen that the window, may be easily raised above its normal lower closed position because of the free rotation of the friction sleeves-1'5 during-such movement; or the sash may be depressed below the window-sill because the operator will always have better purchase on "the sash to push the same down. At the same time, it will be seen may be as easily raised from its depressed position below the window-sill as it is raised above the window-sill by reason of the free rotation'of the friction sleeves 15. Nevertheless, afterany movement of the window has it will be firmly held in adjusted position above or below by the improved friction device here disclosed. 1

While I have shown and described and have pointed out in the annexed claims certain novel features of my invention, it will be understood that various omissions, substitu- ,tions and changes in the forms and details of the device illustrated and in its operation may be made by those skilled in theart with-. out departing from the spirit of my invention.v

What I claim is:

1. A window-supporting device adapted to be mounted on a window-sash, comprlsing a bowed spring having a friction sleeve mountedthereon, means within the sleeve to permit that the sash I said sleeve to rotate freely in one direction whereby when said sleeve is pressed against the window-frame by said bowed spring the sash will be held firmly in adjusted position, and a fiuted'weaIt-strip mounted in thewindow-frame adapted to cont-act with said sleeve.

2. A supporting device for a window-sash comprising a bowed spring adapted to be rigidly secured at one end at the edge of the sash, said spring having a friction sleeve mounted thereon, said sleeve being knurled or roughened on'its outer surface, a ratchet member mounted on said spring and within said sleeve, friction rollers interposed between said ratchet device and said sleeve and. arranged to permit said sleeve to rotate freely in one direction, but to prevent rotation thereof in the opposite direction.

- 3. A window-supporting device comprising a spring member adapted to be mounted at the edge of the window-sash, said spring member having supporting arms, a friction ratchet member mounted rigidly between said arms, said ratchet member having transverse grooves of a depth decreasing from the interior to the circumference of said ratchet member, a friction; roller pin in each of said grooves, a sleeve enclosin said ratchet member and said pins/where said sleeve may rotate freely in one direction andto be held against rotaton in the op osite direction so that when said sleeve is orced against the window;frame by said spring member the sash may be held in any adjusted position with respect to said frame.

4. A supporting device for a window sash comprising a bowed spring. adapted to be rigidly secured at one end to the edge of the sash, said spring having a friction sleeve rotatively mounted thereon, said sleeve being knurled on its outer surface, a star shaped ratchet member rigidly secured, to said spring and mounted within said sleeve, said member being shaped to form in connection with the innersurface of said sleeve, roller seats, said seats being tapered atone end whereby the friction of the roller in that end is increased and whereby the roller is freely rotatable at the other end, rollers interposed in said seats I and adapted to permit the sleeve to rotate freely vinone directionbut to prevent rotation thereof in the opposite direction, and a fluted wear-strip mounted in the window frame adapted to contact with said sleeve.

In testimony whereof I have hereunto set my hand.
